TO ALL WHOM IT MAY CONCERN:

Be it known that I, A. KOMP, of 184 Fulton strect, iu the city, county, and State of New York,'ha.ve invented a new and useful improved Apparatus for Crushing and Pulverizing Quartz and other hard substances; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to maltc and use the same, reference being bad tci the accompanying drawing, forming part of this specification, in which drawing- I Figure 1 represents atrztnsversc vertical section of mm invention.

Figure 2 is a longitudinal vertical scctionof the same, the line a: x, fig. 3, indicating the plane Of section.

Figure 3 is a plan or top View of the same.

Similar letters indicate corresponding parts.

This invention relates to an apparatus for crushing quartz, stones, and other hard substzu1ces,"iu which the substance to be reduced is exposed to the actionvol' an oscillating and of a revolving jaw insuch a. manner that the same is drawn in between the crushing surfaces by the action of the rcvolvingjowxor roller, and then crushed and ground by the combined action of the two jaws. The required motion of th,e.oscillat-ing- -jaw is efi'cctedrby connecting the same with a similar jaw, acting in combination with a second revolvin jaw, and by' eccentrics, cranks, toggle-joints, or other suitable means, secured to or actuated by the shnfts-of'thc revolving jaws,in such a. manner that, while one of the oscillating jaws swings towards its revolving jaw, the other swingsfi'om: it, and vice versa, and that a large quantity of quartz or other material can be crushedwitlilcomparativcly little; expenditure of power. Elastic cushions, which are combined with the rod or rodsconnccting, the two} oscillating jaws, prevent injury in case a hammer, chisel, or other piece of iron, or simil'armatcrial, should puss: in' twecn the working surfaces of the crushing jaws.

A represents a. frame, which is made of cast iron or any other suitable material, and which forms the bearings for the shafts B B of the revolving crushing jnws C G", and for the, gudgcons or rock-shafts D D of the oscillating jaws E E. The revolving jaws are made of cast iron or any other suitable mutcrial, and they no geared together by strong gear-wheels F, so that they revolve. in opposite directions. The oscillating jaws are also made of cast iron or any other suitable material, and theyprovided with. toes a (2, extending under the revolving aws in such i manner that, when the upper end of the oscillating jzrw swings off from the revolving jaw, the toe of said oscillating jaw approaches the revolving jaw, and vice verso, and by these means the quartz or other substance to be reduced is drawn in between the,- crushing surfuccsiby the action of the revolving jaws or rollers, andthen first crushed by the action of the upper part of the oscillating jaw, and afterwards ground by the combined action of the toe and its appropriate revolving jaw. The two oscillating jaws are connected by a rod or rodsfG, passing through their upper ends, and-secured in place by nuts 6. With each rod are combined two elastic cushions, .c, which are so arranged that the oscillating jaws are cll'owedto yield to a. certain degree, and thereby injury to the apparatus is prevented it a. hammer, chisel, or other piece of similar nature passes in between 'the crushing surfaces of the jaws. The required motion of the oscillating jaws is produced by the action of the eccentric-disks d, which are mounted on the shafts B B, and act on friction-rollers a, pivoted to the sides of the oscillatingjaws. Instead of eccentric-disks and friction-rollers, simple cranks or togglearms, or other suitable devices, might be employed to produce the required result. The motion of the oscilluting jaws is so regulated that while one of said jaws recedes, the other advances, and nice vcrsa, and consequently the apparatus grinds on one side, while its other side crushes. By this arrangement the power is uniformly distributed, and the apparatus is not liable to be overstrainod, and the material to be reduced is crushed and "then ground, all in one continuous operation.

What I claim as new, and desire to secure by Letters Patent, is-

The oscillating, crushing, and grin lingjaws E E, in combination with the rerolvingjuws C C, constructed substantially as and for the purpose described.

This specification signed by me this 8th day of March, 1867.
